Quantum bitcoin mining

6 Jan 2018 “The second someone creates a viable quantum computer, the NP-complete math problems at the heart of Bitcoin mining tech become instantly solvable,” Beath notes. “In other words, one answer to the question 'what's the first thing you'd do with a quantum computer?' is 'mine all of the remaining Bitcoin

There are two threats to consider here. First would be using Grover's algorithm to speed up Bitcoin mining. The second would be using the elliptic curve analogue of Shor's algorithm to solve the discrete logarithm problem to break the digital sign
